Hi:

You need to use a minor number that is less than the 'maxvgs' kernel value. You could use '0x06' or '0x01'.

I was discussing this with my colleague

the number of VGs is anyway less than 10
so..why cant I create with the minor number 0x0a0000 or 0x0b0000 something like that?

also.. how should i create with mknod 0x650000 (as per my design document)
i tried...it gave me error.

ultimately i used unused minors (0x010000 and 0x060000) ;-)

If you want to use 0xa..... than increase the maxvg value than only u will be able to use this.
